Well nostalgia, however you slice it, is "a neuronic command" according to this article, and yah know what? I get it. We're connected to the "high drama" of our youths like sick fools, and I love it.
This article is chock full of fun brain and music facts, which have become my favorite facts as of late (too bad I figured out how to combine Biology and Music PERFECTLY at the age of 26 instead of 16). Neurons sync to beats and lyrics help shift attention - how cool is that?? And you know the chemicals within us are the main source of it all. Because adolescence is when our brains are on overdrive in development, we're gaining imprints from this music more so then than ever.
This all seems obvious, I'm sure, but I still adore that there's an explanation. Check this article out for yourself, then get the High School Mega Mix pumping… even if you're like me and it's a bunch of Dashboard Confessional and Something Corporate that'll drive you to tears.
